The belief system of Theism, which is the idea of a deity that creates the world, is called theism. It is also called the concept of Platonic cosmology. This philosophical approach ignores the essential role of experience in Theism. We would miss the essence of Theism if we ignored experience.
Arguments
There are many reasons to support theism. First, there's the morally-good agent argument. It is based upon a thought experiment where an agency helps a victim of car breakdown by paying for a truck or flagging them down. This argument could be used to argue that the agent is best positioned to help the car-broken victim, even if they don't believe in God.
Another argument in favor of theism is often called the probabilistic proof of evil. This problem holds that God's existence is incompatible with free willful evil. Therefore, a good god would be able to prevent such problems. This argument is not supported by all people.
Sub-divisions
There are many sub-divisions to theism. The pro-theism positions are listed in the first column. There are others, which can be further subdivided, as well. As more general answers are found, we expect this chart to grow. These distinctions can be important for different reasons. Some people argue it is difficult to defend broad personal/impersonal theism. Others argue it is possible to be both narrow and broad personal anti-theists.
Theism can also be subdivided into two sub-groups: agnosticism and atheism. Although atheists don't believe in formal religions they might have strong spiritual beliefs. They may believe or have faith in fairies, angels, karma or some form of divine plan. They may even believe in ghosts and Ouija boards.
Morally Good Agents Argument
The Morally Good Agents Argument against theissm posits that a deity is not all good. If a deity was all good, then there would be no reason to allow evil. The same goes for deity who created a world of moral evil.
To avoid this situation, God must have created significant free people. However, these free agents would commit evil in at least one world. God could not have created an ideal world that had morally good agents in all worlds.
Platonic philosophy
The compatibility of Platonic philosophy within Theism is a matter of debate. Platonism and Theism were historically incompatible. They do however have their differences. One of these is the belief that God is the creator of everything.
In Platonic philosophy, God is the creator of all things. He created the cosmos, and created humans. What about the relationship of God and humanity? Both are based on belief.
Conflicts with traditional theism
Disagreements over religious beliefs can lead to conflicts with traditional theism. It is possible to disagree about the nature or existence of God. The belief that God is good and omnipotent can be incompatible with the existence or evil. On the other hand, a person may hold ethical commitments that conflict with traditional theism. One could, for instance, believe God is not capable or willing to allow evil.
There are also many differences in how the divine attributes are defined. One theists see God as omnipotent. They also consider him to have omniscient and omnipresent attributes. However, others view him unchanging without beginning or ending. Others argue that God is neither eternal or finite, but rather an individual with characteristics such love and knowledge.
